DESCRIPTION: Flare ribbons are a quintessential part of a flare. They are e
 xtensively used to understand the overlying reconnection mechanism and ove
 rall flaring process. Further\, the reconnection rate is a key parameter i
 n the magnetic reconnection process. But it is difficult to estimate the r
 ate from direct observations at higher heights in the solar atmosphere. Ho
 wever\, flare ribbons are believed to be one of the major energy depositio
 n sites and the imprints of reconnection occurring at higher altitudes. Ut
 ilizing this advantage to map the reconnection rate at the corona\, Qiu et
  al. (2002\, 2006) had provided an approach to estimate the flux and flux 
 rate in a flare. In the talk\, I will discuss about the application of thi
 s method to multiple wavelengths in the solar atmosphere using high resolu
 tion data from ground-based Multi Application Solar Telescope (MAST)/Udaip
 ur Solar Observatory in Ca II 8542 line\, and data in UV and EUV channels 
 from the Atmospheric Imaging Assembly (AIA) and Helioseismic Magnetic Imag
 er (HMI) onboard the Solar Dynamics Observatory (SDO). I will highlight th
 e interesting profiles of reconnection flux and associated rates for all t
 he channels in ribbon (sub)structures\, along with the probable nature of 
 reconnection occurring there. The work also explains the triggering mechan
 ism behind the reconnection in 3D using the non-force-free-field (NFFF) ex
 trapolation model.\nSpeaker: Sushree Sangeeta Nayak
